Windows/Mac/Windows Mobile: Live Mesh, the cloud-based Windows Live service that can synchronize files to the cloud or across computers, has gotten quite a few updates since we last checked out the "tech preview." Biggest amongst them is a new dedicated Mac client, which adds a toolbar control panel and offers a similar desktop experience of designating folders to have their content synchronized to your 5GB of online space, or to another computer directly. There's also a Windows Mobile version, international restrictions have been removed, and mobile phone browsers (even iPhones) can get access to their files at http://m.mesh.com. Check out the numerous other changes and tweaks at the Live Mesh team's blog entry below. Lifehacker Headquarters' Mac team doesn't come in until later this morning, so if you've given Mesh a spin on your Mac, tell us what you thought of it. Live Mesh is a free service, requires a Windows Live log-in to access (and may be in slightly limited beta with new features).
